- ID:OM Memory Errors in DESQview
- Quarterdeck Technical Note #114
- by Stan Young
-
- An out of memory message when loading a program means one of three things:
-
- 1. There has not been enough memory allocated to the program and the
- program is giving the error message. In this case, run DESQview's Change a
- Program and allocate more memory (in the Memory Size in K field). Remember,
- regardless of the total memory on your machine, the program will only see
- what was allocated to the window.
-
- 2. You have allocated too much memory to the window and DESQview is giving
- you a message indicating it doesn't have enough free memory to make the
- partition that big. Try making the figure in "Memory Size in K" smaller.
- Run the DESQview Memory Status program and check the figure listed in the
- field Conventional Memory/Largest Available. This figure should give you a
- clue as to the maximum size window you can open after allowing for an 11K
- overhead if you are loading a text based program or 22K for a graphics based
- program.
-
- 3. You may have entered a value for "System Memory (in K)" on the advanced
- options menu of Change a Program. For non-DESQview specific programs, this
- figure should always be zero. Even in the case of DESQview specific
- programs, this figure would rarely be above 10K. Having a figure in this
- field increases the overhead for the window by a corresponding amount.
-
- When selecting a memory size for your application, you should consult the
- program's user manual to see what the developers feel is the minimum memory
- requirement. Usually, this is stated in the early portions of the manual or
- sometimes on the box that the manual came in. Generally you can deduct
- 30-40K from this number, since these numbers are generally given in standard
- "round" machine sizes and account for the overhead of loading DOS and a few
- drivers. This overhead need not be calculated as part of the DESQview window
- size.
